Bob, Thanks for those additional T-coil links, I hadn't seen either of them before. For the problem at hand of matching a part with big input C, for 1 Gbps-ish data, I'm not sure how practical it actually is to do broadband peaking for a wide bus at the board level using discretes; when I've considered it in the past, the thought of trying to add all those extra parts and their associated parasitics without just making things worse has put me off the idea. The nice thing about the "stick an attenuator on it" approach is that it'll help match anything - input C, package, vias, etc; i.e., when seen through a 6 dB pad, anything has a return loss of at least 12 dB. ( although those nifty differential 0404 "O" attenuators don't address common mode signals ) Brian --- In si-list@xxxxxxxxxxxxxxx, Bob Ross <bob@...> wrote: <snip> > A new book is available from Springer by two Slovenian authors, > Peter Staric and Erik Margan, on "Wideband Amplifiers" cover some > of the T-coil technology and extensions: > > http://www.springer.com/sgw/cda/frontpage/0,11855,4-102-22-70230149- 0,00.html?changeHeader=3Dtrue > <snip> > > Another research reference showing a recent T-coil application > for ESD circuits is: > > http://www.ee.ucla.edu/~razavi/papers/Journals/G&RDec03_1.pdf > ------------------------------------------------------------------ To unsubscribe from si-list: si-list-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field or to administer your membership from a web page, go to: //www.freelists.org/webpage/si-list For help: si-list-request@xxxxxxxxxxxxx with 'help' in the Subject field List FAQ wiki page is located at: http://si-list.org/wiki/wiki.pl?Si-List_FAQ List technical documents are available at: http://www.si-list.org List archives are viewable at: //www.freelists.org/archives/si-list or at our remote archives: http://groups.yahoo.com/group/si-list/messages Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu
